Howdy!

I just bought a gorgeous Aglaonema from a local shop and over the first week I've noticed a few issues with some of the leaves.

One looks to be getting crispy.. is this from direct sunlight? It was in direct light for probably an hour or two... The other photo shows the leave decomposing to a sort of gooey/sticky substance.. If I pulled at it I'm sure it would just come right off and onto my hand...

I had been misting the leaves with a spray bottle as I made my rounds with all my plants each day, could this be a sign of too much misting collecting on the leaves?

my 2 cents--
The crispy edge is a cut edge, healed, not to worry.
one gooey leaf?, cut it off and discard and forget it.
stop misting, as it is not necessary nor effective.

Beautiful plant, though I seem to have less ease of care with these pink ones than the old green and silver types. Limited experience tho, I've had 2 kinds of red/pink Ags.
i'm pretty OK today, how are you? ;^)

The leaves may be reacting to some damage done to the roots during repotting. The plant may also be reacting to some possible cold or chilling damage done during its car ride.

Finally, I would note that it's getting too much sunlight in that location. It does like very bright but INDIRECT sunlight and that means it is definitely getting too much light exposure on sunny afternoons. A north-facing window would be better. Otherwise, move it back from or off to the side of the window it is now in.

Hey! Ok, so since your reply, I have moved the plant away from the sunlight and it has not been getting any direct light. Watering is once every week-two; new leaves are growing and there is a new stem growing out of the soil, HOWEVER, a few leaves have started to succumb to the issues, getting soft and goopy (see photo). I've cut each of the leaves off but do you have any idea what causes the leaves to get soft, goopy, and eventually disintegrate?

Soft watery leaves can be caused by exposure to cold or by damaged roots. Root damage most often occurs either during repotting, especially if some of the original soil was removed and/or by subsequent overwatering.

Can you post a photo that show how it is potted?

Hey Will,

Attached are some photos of the pot it is in (no nursery pot, the soil is sitting directly in the planter) There is a drainage hole in the bottom and a drainage plate as well so it is never sitting in water... It came like this from the store I got it... I am not sure if they repotted it right before selling it to me or not... but more new leaves are growing and a huge white stem seems to be poking out of the soil as well (in photo).

Let me know what you think good sir!

Let's hope it is just residual damage done to the roots when the store repotted it. Be careful not to overwater it by allowing the top inch of soil to get dry to your touch before you water.

Hey Will, So I haven't watered it for almost two weeks now as the absolute top layer of soil still feels a tad moist and attaches to my skin when I feel it.

However, over the last couple of days, I have noticed some troubling signs on two leaves. Instead of getting brown, they seem to be turning black which is scaring the crap out of me. Have you ever seen anything like this? In my previous posts, I showed the leaves with brown spots on it, so I decided to cut them off with sterile scissors at the root, could they be reacting to this?

In addition, even with these leaves turning black as you can see in the 3rd photo new leaves are flowering and the white stems are still shooting up from the soil.

Golly gee this is a confusing bugger!

I've killed the only aglaonema I've ever owned and I did it with overwatering. I was watering it every 3 weeks, but the plant was still in the 'big box' self-watering planter from the store which had a drainage hole. The self-watering part was that the water never really drained properly and simply pooled in the lower layers of soil. I didn't know that. The leaves got either soft and gloopy or went completely yellow from the stems up. I didn't figure out the problem fast enough.

From my one experience, I would say that if the top layer of soil is still wet after 2 weeks, the water isn't draining away properly and the roots are suffocating.
Keep calm... and plant something.

The nursery moved your plant into a larger pot with added soil that is like a sponge and takes longer to dry out. So that is not surprising. However, as @hlutzow has pointed out, if the roots stay in wet soil for too long they will suffocate. That means that when you water you should give it just enough so that the soil gets appropriately dry again within 1-2 weeks.

The dieback of some older leaves is normal. As long as the new leaves are remaining healthy then you are probably on the right track.
